! We introduce a new error-correcting code for biased-noise qubits. Built from the concatenation of two classical codes, it outperforms the surface and XZZX codes when the noise bias exceeds 7x10^4.

Elevator Codes: Concatenation for resource-efficient quantum memory under biased noise
Biased-noise qubits, in which one type of error (e.g. $X$- and $Y$-type errors) is significantly suppressed relative to the other (e.g. $Z$-type errors), can significantly reduce the overhead of quant...
